Email, CRM & Support
Retention email, helpdesk, and the bot that answers first.
Acquisition gets the budget and retention pays the bills, which is why this category is usually underfunded until the first bad review wave. The email tools here are judged on deliverability and segmentation depth rather than template prettiness, because a beautiful campaign that lands in promotions has done nothing. The support tools are judged on the same thing from the other side: whether the bot deflects the repetitive question without inventing an answer to the one that matters. Both carry a compliance obligation — consent for the list, retention limits for the conversation history.
